Description
Technical field
The present invention relates to a kind of rubber manufacturing machinery, specifically a kind of five compound rubber extrusion device head devices.
Background technology
In existing tire production, in general, tyre surface/sidewall semi-products are produce by two compound extruded units, tri-extruder group mostly, also the tyre surface having some high-grade/sidewall semi-products produce with four compound extruded units, but two, three, the four compound extruded units tyre surface/sidewall of producing, some also need carry out film laminating to its surface machine is outer.The dimensional accuracy that this machine is fitted outward can not meet modern high-grade radial to the dimensional accuracy of its product and dynamic balancing demand.Therefore the high-end demand that more five complex extruders of the compound number of plies in machine consist of market is researched and developed.
Compound in the pure machine that compound in the machine of existing tire production is added that upper part machine is fitted outward by five compound rubber extrusion device groups, the technique of the outer compound of machine changes various ways into, five kinds of different sizing material compounds in machine are applied on the tyre surface/sidewall of tire by it, make the laminating between various sizing material tightr, the size of each parts is more accurate, thus meet the kinds of processes requirement of modern high end tire production, optimize the manufacturing process of tire.This equipment is applicable to five compound extrudeds of high-grade radial semifinished part, will be one of important process equipment in high-quality radial tyre production.Its use for improve tire product quality, raise labour productivity, reduce energy consumption and raw materials consumption, all will play important effect.
Five compound rubber extrusion device groups increase an extruder than four compounded rubber extrusion group, and it mainly comprises five compound rubber extrusion device heads and five extruders, and the machine barrel of five extruders is connected with each crowded material mouth of five compound rubber extrusion device heads respectively.Machine barrel due to extruder is large and grow, and extruder need be configured with Large Reducer and electric motor, feeding conveyer belt and complicated frame to be built around extruder, make the on-the-spot mechanism of five compound extruded units more, space structure is more complicated, and floor space is larger.In order to make full use of space, reduce floor space, distribute rationally, key is the position effectively arranging five extruders, makes matching component rational deployment.
Rationally will arrange the locus of five extruders, mainly rationally determine the connection angle of each machine barrel and complex extruder head, connection angle is excessive, then after five extruders stretching, extensions, shared locus is large; Connection angle is too small, then the matching component of five compound extruded units likely location conflicts occurs, and shelf position is narrow and small, and one is the operation being unfavorable for direct labor, and two is the Maintenance and Repair being unfavorable for equipment.
In addition, the difference of the level inclination of the extruder crowded material mouth of complex extruder head, the stress suffered by different parts of each parts and each parts in complex extruder head can be made different, therefore, the setting of the inclination angle size of each crowded material mouth of complex extruder head, is related to the multinomial performance index of extruder head device.
Along with angle different of complex extruder head mould body die joint and horizontal plane, the stress that die body component is subject to is also different.Larger angle, the horizontal component be subject to causing die body is excessive, thus makes the work deterioration of locking device.
The length of each flow passage chamber of complex extruder head also will have a rational scope, and length is excessive, and sizing material is overstand wherein, and sizing material temperature raises too much, causes extruding output and reduces; Length is too small, and screw can not be transformed into laminar flow wherein by sizing material effectively, thus causes sizing material to extrude size instability, and sizing material extrusion pressure can not set up good pressure simultaneously, and the compactness of extruded product is not fine.
The key technology of compound rubber extrusion device head comprises: the level inclination size of each extruder crowded material mouth, the level inclination size of each die body die joint, the length range of each flow passage chamber.Although there has been four compounded rubber extrusion device head now, but for making the compact conformation of the five compound rubber extrusion device groups adding an extruder, rationally distributed, the level inclination size of each crowded material mouth of five compound rubber extrusion device heads, the level inclination size of each die body die joint, the length range of each flow passage chamber still needs to redesign, and namely needs a kind of five compound rubber extrusion device head devices of optimal design.
